When two plane mirrors are tilted at an angle of 72 degrees, six images are formed. The first two images are the direct reflections from each mirror, and the remaining four images come from the multiple reflections between the mirrors.

The answer depends on the angle between the mirrors. The distance between the mirrors does not, in theory, make any difference. If the angle between the mirrors is x degrees, then the theoretical number of images is (360/x)- 1 which is rounded down. In practice, minor defects in the mirrors, refraction, total internal refraction, absorptions, scattering etc will reduce the number of images.The answer depends on the angle between the mirrors.

Because - if the mirrors are exactly parallel - they will reflect each others image indefinitely.

No. They will look different.
